There have been several posts on this topic of getting more features available in IR3.5.2+ to run in JServer 3.5, specifically the barcode (barcod4j/barbecue) support. Adding the newer JasperReports jar files does not solve the problem, adding the barcode jar files does not solve the problem. Is there a solution? Is there any way to get these classes available for use in JasperServer 3.5 ? If so, how, exactly. Thanks.
